Education & Professional History

University of Notre Dame, BS; University of Cambridge, MASt; University of Chicago, MS

I got my PhD in 2020 from the University of Chicago. My advisor was Danny Calegari. I graduated with an MASt in Mathematics from Cambridge University in 2014, and a BS in Mathematics and Music (Vocal Performance) from Notre Dame in 2013.

I’m interested in geometric group theory, especially questions about random groups and cube complexes. The first papers I read in graduate school were by James Cannon: The Combinatorial Structure of Cocompact Discrete Hyperbolic Groups, and The Theory of Negatively Curved Spaces and Groups. While I read these in graduate school, they are accessible to any undergraduate familiar with groups. For any undergraduates interested in geometric group theory, I highly recommend them! For a more systematic approach to GGT, I also recommend the book Office Hours with a Geometric Group Theorist, edited by Matt Clay and Dan Margalit.

Here is a statement on my research, including potential projects with undergraduates.

Vocal Biography

MurphyKate Montee, soprano, lives in Northfield, MN. Her performance experience includes concert and chamber works, including the soprano solo in Haydn’s Missa in Angustiis and the role of Lieschen in Bach’s Coffee Cantata. In 2014, she performed the role of the Countess in Mozart’s The Marriage of Figaro in a concert setting, where she was lauded as “rich-voiced, impressive” (Sardines). She has also performed in dramatic settings, in stagings of Tobias and the Angel (Edna), Dialogues des Carmelites (Blanche de la Force), and Sweeney Todd (Mrs Lovett).

MurphyKate studied under Patrice Michaels while earning a PhD in Mathematics from the University of Chicago. In 2013, she graduated from the University of Notre Dame with a BS in Music, where she studied Vocal Performance with Mark Beudert.
